NIRMaster™

FT-NIR top performance

Control the quality and nutritional facts of your feed, pet-food, milling and bakery products rapidly. The NIRMaster is the world’s first dedicated FT-NIR standalone spectrometer available in food-grade PMMA or stainless steel. The accuracy and reproducible performance of polarization FT technology plus the hygienic design with certified dust protection meets the easy cleaning processes requested for at-line machinery.

The BUCHI polarization interferometer

BUCHI has adapted the successful quartz polarization interferometer by using crystals with a very high refractive index. This leads to optimum resolution and a compact design maintaining the advantage of insensitivity to mechanical disturbances.
The reason for the superior performance of this interferometer in rough environments is the difference of spatial movements and the optical path shifts for the two light beams in a birefringent crystal of variable thickness. Whereas in a Michelson type interferometer mechanical distortions directly affect the interference, such effects are reduced by a factor of 10 to 20 in a crystal interferometer.

Easy-clean design increases food safety day by day

The hygienic easy-clean design and high ingress protection (IP) support your routine work in harsh environments. The NIRMasterTM is available in food-grade PMMA housing or stainless steel housing with IP54 or IP65.

The twin lamp module

BUCHI has set a new standard in terms of the availability of an NIR spectrometer.Our NIR spectrometers are equipped with a twin lamp module, which will automatically switch to a second integrated lamp in the event
of a failure of the primary source. This minimizes the risk of an instrument failure, and sufficient time is left to order a replacement lamp. Meanwhile you can continue your measurements without further intervention.

What are my commercial benefits of using NIR spectroscopy?

Research and quality control laboratories benefit from NIRS alike. While researchers can accelerate their experimentation, QC departments benefit from the ability to analyze hundreds of samples per day – both saving substantial amounts of time and money.

Do I need to calibrate my BUCHI FT-NIR spectrometer?

There is no need for instrument calibration. The term “calibration” is used in NIR with two different meanings:

Unlike other NIR instruments, the BUCHI instrument does not need to be calibrated since the accuracy is ensured by internal standards and permanent laser-aided alignment.

In NIR spectroscopy a calibration model is generally required to interpret sample data. This model needs to be developed on setup of the application. BUCHI’s NIRCal software makes it straight forward to develop robust and reliable calibrations by correlating NIR data with reference analytics.

Can I work with a BUCHI spectrometer in any environment?

Yes, the NIRFlex N-500 is a benchtop spectrometer mostly for laboratory use. The NIRMaster™ and NIRMaster™ Pro provide high ingress protection and are therewith ideal for benchtop analysis at production sites. The NIR-Online™ provides analyis in real time directly on the prodcution line.

What is the optimal resolution for an NIR Spectrometer?

For modern instruments 8 cm-1 resolution is optimal for NIR measurement. As NIR spectral bands are relatively broad, higher resolutions do not improve the performance of NIR application. On the contrary, higher resolution spectra have a poorer signal-to-noise ratio within a given measurement time.

Options

NIRMaster with food-grade PMMA Housing - 11057000

Different needs, different working environments demand different types of instrument housing. To supply a FT-NIR spectrometer which suits your needs, BUCHI offers stainless steel and food-grade PMMA housings that are ingress protected.

NIRMaster Pro with Stainless Steel Housing - 1105710

To reduce the risk of chemical contamination, the suitable housing materials should be considered. Both food-grade PMMA and stainless steel housings provide good resistance against organic acids, salt and alkalis at moderate temperatures. To prevent the risk of bacterial contamination, regular cleaning is mandatory. The NIRMaster helps you with ingress protection (IP) and hygienic easy-clean design.
